Welcome to NGA,
@BugLady !
if the eggs/larvae are in the soil of the plants it would be highly unlikely that you would see them. I would recommend moving the plants out of the kitchen (to the outdoors, or a garage, if possible), and letting them dry out considerably. What kind of plants are they? Would it be possible to remove essentially all of the soil from the plant(s) and repot them in new planting mix?
